- To all whom it may concern:

Be it'known that I,- ALBnR'r PIH NT, a

citizen oft-he United States, residing at Chi desiccation of milk. I 1 15 One form of-my invention is illustrated in the accompanying drawings, wherein- Figure l is a side elevation with parts broken away; Fig. 2 is a front elevation with parts broken away; Fig. 3 is a cross zosection with parts removed; Fig. 4 is a detail cross section.

Like parts are indicated by the saine let} a ter in all thefigures. 3

A, A are the side frames on which is mounted the case B'shaped as shown or in any desired manner and having the receiving' chamber C below in which rotates the com'eyer C which discharges into the spout C and is driven by thepinion C on'the shaft C, such pinion being driven fflom the shaft 0 The'case has an upper compartment 1) preferably perforated at the top at D D to permit of the introduction ofthe liquid to be desiccated. D is a hotair'pipe havinthe groups of laterally opening apertures D? D It is supplied by't-he fan D from the air heating chamber D 'The case has an intermediate chamber E in which is mounted the separator. I have called these three chambers for convenience, the upper one the drying chamber, the intermediate one the separating chamber, and the; lower.

one the collecting chamber. The intermediate or-separator chamber, E has at-one end the air discharge pipe E opening intothe tan E with the discharge end E which opens into the box' E, the upper-portion of which has a collecting box E E is a cup opposite the opening E into which the air is received, as indicatedby the,

arrows. v

F is a ring shaped as shown and having a series of projecting fingers F There are two of such rings and they are connected by outer slats-F some of which are indicated in 3."; -;lhese slats are secured cleaning brush which is intended to pass upwardly between the sections of the drum and or screws driven therethrough into the outer end of each finger. The rings are also-connected by the transverse ribs F secured each at each end by a screw F to the ring. Intermediate the slats and ribs are sheets of wire gauzeli. The rings, slats, ribs. and

-wire gauze make up a drum or cage which is mounted at eachend in one. of the frame pieces A by means of the short'thimhle G, which is provided'wit-h the exterion ratchet wheel'Gr and is inserted inside the ring F i and secured thereto by a series of (nails or screws G G The thim'ble passes through a suitable aperture in'the wall of the case 7 0 B as indicated in Fig. 4. The samearrange 'ment can be employedfat each end. The

separating drum is thus mounted so as to be; rotated step bystep in a forward direction by means of. the ratchet wheelsat its ends. It is arranged so as to snugly fit the lower end of the case "and substantially fill the' separating chamber and so as to be inter: posed between the upper or drying chamber in the case and the lower or collecting cham- .30-

J .is a guard shaped as shown and turned up. atone end at J and secured by one or more screws J 2 to'the' upper enlarged portion of the standard A. At its other end it has an upwardly extended portion J with a' ring J whichihangs upon the inwardly projecting pipe E.{ In this manner the guard is heldfixedly in position within the separating drum and so as to cover the lower sections thereof. The sides/0f the case are slotted .at- K K to permit the vertical move ment of the rod K which carries the brushes K The rod and brushes together make a brush the dried or desiccated materials from the sides'of the collecting screens.

The mechanism for operating the drum and the brush is shown in elevation at one end but it'will be understood that the parts may be duplicated so far as that is .neces-,

sary, at each end of the drum and brush.

At the-end of the rod K is a wheel K over which travels the .belt K" aroundthe two small pulleys K", K, and thelarge pullle y K Thus whenever the latteris driven the brush is rotated, the parts .being mounted as-indicatedso that this is tru'eno matter; what the position of the brush.
